'i tl'iedirection of rotation ofthe shaft 2, Without change in p -it tointerlock with the gear l2. When thus adjusted,'

i corresponding variation Willfollow in the power transthe speed, therod 3 is-shiited toward the left, moving the lclutch sleeve 18 from theposition shown in Fig. l to'- that shown in Fig. 3, to disengage it fromthe gear 1l, which thereafter turns loosely upon the shaft and causetransmission from thedriving shaft to thel driven shaft is through gearsl0, 14, 13 and 12. j

With the gearing adjusted as in'Figs. 1 or 3, for a Vtwo to one drive,rany load upon'the driven shaft in excess of the total resistanceoffered by the weight and friction of the engaging. parts of th'egearing will cause the casing andreducinggears 13 and 14 carried therebyto revolve about the driven gears 11 and 12 and the driven shaft willcease to rotate. in order, therefore, to counterbalanee the load ,Iafriction band brake 23, or other suitable friction device is employed inconnection with the easing and as will be seen, by varying this'friction, a

mitted, permittingtlie driving shaft to be run continuously in onedirection at full speed, while the driven shaft,`wl1en rotatingV in thesame or in the opposite di- ,r/etion may be caused to make any number oirev0lu- 'tions up to the maximum number for which it is geared.

Referring nouw to Fig. 2. when the shafts; as shown, are coupled .directfor the transmission of high speed, it is desirable that the drivinggearl0, should run free, as otherwise the entire mechanism would rotate as aunit. This would follow, as will be evident, since the gear l11,connected 'throughfthe clutch 18 with the shaft 2, can not rotate at theced of the gear l0 upon the shaft 1,

4and hence, the entire train would be locked, For the purpose,therefore, of causing the gear 10 to become disconnected from thedriving shaft at 'such times, it is notched as indicated at 24,to'ree'eive a key 25, which is carried by a pin 26,',spring-seated inthe soeketed end of the driving shaft. As arranged, the spring 2 7,advances the key into locked relation with the'gear and the disengagement thereof is effected by the rod 3, when shifted to the limit ofits movement toward the right. With the gear l0, running free and thefriction 23 applied, the

above described are made without moving the gears in',

and'out of engagement; also that the speed and direction of rotation ofthe driven shaft is under complete control and may be varied graduallyor suddenly as required.
